At Burning Man 2006, Nate Smith created an art piece called 2BLEVE. BLEVE is short for “boiling liquid expanding vapor explosion”. It was an astonishing 15 seconds. I saw it from about 1/4′ mile away.

Here’s an excerpt of an email from my friend David pointing to pictures and videos related to it.

2BLEVE. BLEVE is an acronym for “boiling liquid expanding vapor explosion”.
See wikipedia. Also see the BLEVE account in the 1973 section of this.
some interesting quotes: “…two acre fireball…” and “…one thousand feet in diameter…”.
